Underwater Facilities Inspections and Assessments at U.S. Naval Station, Key West, Florida

摘要

The underwater inspection was conducted between 20 and 25 January 1980. It included the sheet steel piling that entirely surrounds Pier D-3 as well as part of the adjacent quaywall. It also included the concrete strucutre of Pier D-1 and two of the three steel H-pipe finger piers that just out to the south from the offshore end of Pier D-1. A visual and tactile inspection was conducted of all the underwater elements of these piers. In addition underwater photographs were taken of selected parts of the operation and structures, underwater video was utilized, and ultrasonic thickness measurements and underwater potential measurements were made of the steel structures. All significant evidence of underwater deterioration was recorded and the condition of the surface and abovewater structure was noted.
